Script for backup

[marjoh05]

I found some script online i need to use for backup purpose. I have a windows server that transfer daily backup to my ubuntu 12.04 server. Because Windows Server Backup wont save more than one backup at once to a shared folder i have a script that weekly copy and rename(renames with the date) and puts it in another folder. The only problem is that the HDD gets pretty full after some months, so i need a script that deletes every file thats older than 4 weeks, but wont delete any if there isnt any more files added(if the backup stops working).

Found a script that deletes all files who is older than 3 days: how can i set it to 4 weeks? Or how can i set it to not delete files when its 4 or less folders in my weekly backup folder?

find /u1/database/prod/arch -type f -mtime +3 -exec rm {} \;

Thanks :-)

Seems like a job for logrotate (http://manpages.ubuntu.com/manpages/precise/en/man8/logrotate.8.html). Also see savelog (http://manpages.ubuntu.com/manpages/raring/en/man8/savelog.8.html).

Answering your direct question, it seems obvious if you know that 4 weeks make 28 days :)

find /u1/database/prod/arch -type f -mtime +28 -delete
